Chemical Engineering Thermodynamics A reasonably general expression for vapour-liquid phase equilibrium at low to moderate pressure is Φi yi P = Yi xi fi° where, Φ is a vapor fugacity component, Yi is the liquid activity co-efficient and fi° is the fugacity of the pure component i. the Ki value (Yi = Ki xi) is therefore, in general a function of Temperature only Temperature, pressure, liquid composition xi and vapour composition yi Temperature and pressure only Temperature, pressure and liquid composition xi only Temperature only Temperature, pressure, liquid composition xi and vapour composition yi Temperature and pressure only Temperature, pressure and liquid composition xi only ANSWER DOWNLOAD EXAMIANS APP
Chemical Engineering Thermodynamics High pressure steam is expanded adiabati-cally and reversibly through a well insulated turbine, which produces some shaft work. If the enthalpy change and entropy change across the turbine are represented by ΔH and ΔS respectively for this process: Δ H ≠ 0 and ΔS = 0 Δ H = 0 and ΔS ≠ 0 Δ H ≠ 0 and ΔS ≠ 0 Δ H = 0 and ΔS = 0 Δ H ≠ 0 and ΔS = 0 Δ H = 0 and ΔS ≠ 0 Δ H ≠ 0 and ΔS ≠ 0 Δ H = 0 and ΔS = 0 ANSWER DOWNLOAD EXAMIANS APP
